Sharp-edged beak best describes the mouth of a turtle.

Answer: Option D

Explanation:

The mouth of a turtle has sharp edged beak in both the sides of the upper and lower jaw. The muscle of the jaw is so strong that it can amputate your finger when it bites.

The mouth has sharp papillae which looks as sharp thorns protruding throughout the esophagus till the stomach. This aids to get a hold on their meals like jelly fish which are generally slippery to eat without grip. It also protects them from their poisonous sting. The papillae contains thick proteins similar to our fingernails.
